Although I may be no music expert, I've listened to a lot of it. And if nothing else, I know what I like.
Many people would bemoan this music, no doubt, as being too predictable, too boring, too simple. But that's precisely why I like it. Almost all music has its place. On The Beach, simple and predictable as it is, has its own place.
Although the music is of simple construction, it isn't bad. The very thing that makes this such an enjoyable album is that each song allows the listener to make a mental connection to some thought, fantasy, or dream. So often, musicians don't bother to write music that does this, but all of this "silly, simple music" does it. In fact, it does it quite well.
I don't doubt that this would not be very interesting live. But that's not its place. It belongs in CDs and recordings, not concerts.
Even in spite of this, the simple compositions in this album are a joy to listen to. Worthy of a listen.
